When I was 16 and my sister was 14 we went to spend the summer with our grandmother in Wisconsin. Our parents had gone to spend six weeks with their church on a mission trip to eastern Europe. A man lived next door to our grandmother and he would watch us. We could see him at the window when we came or left. It was summer so we were in shorts. One day I looked out the window of our room and I noticed him looking into our room from a window in his house. I stood there and he pulled out his penis and started to masturbate. I stood there and watched until he finished masturbating and he had gotten his stuff on the window. He stepped towards the window and with his shirt he cleaned it off and made the fucking motion to me while he held his penis in his hand.

I stood at the window several times while he masturbated and made motions of fucking to me. I took my top off for him and then one day I stood totally naked in the window while he masturbated.

My sister and I were at the supermarket when he approached me and asked me if this was my little sister. He leaned over to me and said he always wanted a girl like her and to bring her over to his house because he wanted to fuck her. When he walked away he reached for my crotch and grabbed me told me he liked virgins.

The next time he spoke to me was at the mall, he asked me why I hadn't brought my sister over to him. He grabbed my crotch again and told me to get over there, he was tired of waiting for her. I took her over the next day while my grandmother was out running errands. Watching him fuck my little sister made me masturbate and have an orgasm. It was the first time I had an orgasm with other people around. After he finished fucking my sister, I helped her clean up and get dressed and told her that we should never talk to grandma about this. She asked me if he had fucked me and I told her not yet, he wanted to fuck her first.

I sat at his kitchen table when he had me suck him. He pinched my nose so I had to breathe through my mouth and stuck his penis in my mouth. He told me to suck hard because he wanted to fill me up. He grabbed my head with both hands and I had a hard time holding my lips around his penis while he fucked my mouth. He got done and I got to taste him for the first time. It tasted good in a weird sort of way, I liked how it felt in my mouth. He fucked me later that afternoon.

After he started fucking us we never did the window thing again, we went over to his house when my grandmother was out and got fucked or we sucked him. We learned how to 'ride' him, and we would take turns getting on and off, we also liked getting it from behind side by side, in one and then in the other one. We both sucked him and we both fucked with him.

We went back home when my parents returned and the following summer when we went to my grandmother's a couple with two kids was living next door. We had our summer of fun. When we got married we were not as innocent as we appeared, we had already had the real thing.
